srp_arp_thegarbage_v4_9 missing textures

On the map “srp_arp_thegarbage_v4_9”, There is no floor (Just Blank as if it were never there). There is still collision data obviously, but floor texture is completely missing. Can someone tell me the requirements for the map so that I can actually play it.



Still looking for help


Garry’s Mod 13 appears to have broken the map. Me and several others were trying this out for a server the other day. After we all tried it out in single player, we got extreme console spam, under 5fps, and half the map appeared to have invisible textures.

We all have all Source content too. I know this map was working before the GM13 update, but it’s not anymore.
